I have a problem here. I have a FADAL VMC20 mill, and the following issue has been happening:
I am trying to send a program to the VMC that is about 188k. The machine's memory is 20k. The manual to the Fadal clearly states that it is initially set to 7 data bits, Even Parity, 1 Stop Bit. So, I set CIMCO Edit to that.
Now, here's where the problem is. When I set the baud to 9600 and turn off flow control (under port settings tab), the machine will only take data until the buffer is full (obviously, since CIMCO isn't being told to stop or resume sending).
If I set a delay of 150ms between lines, it will run, but very, very slowly (again, of course, because of the 150ms delay). If I turn on flow control, CIMCO will just sit there, sending nothing to the VMC.
If I use Fadal Assist, and drop the baud down to 1200, it will work as well. Again, very slowly. If I up the baud in assist to something acceptable (like 9600 baud), the mill takes about 29-30 lines and halts, the PC keeps sending data behind it, and errors.
So why am I getting this bottleneck? How should CIMCO be set up to properly flow data to the VMC? The VMC has 20k... do I have to just break down and get more memory for the thing? PLEASE HELP!
I'm not sure how old your machine is, but if it is an older model, you should
prep with cd,7 at the control for 4800 baud, cd,9 for 9600.
if it is an old machine it may only run at 4800, and if memory serves assist
will only do 4800.
heres how I would do this with assist, at enter next command prompt
type in CD,7
set up assist for the correct baud of 4800
select dnc and fire the program at it.
that should work, if not something else is wrong.
I hope that helps.
